On Sunday, December 2, the Boston music community will gather to celebrate its best and brightest at the 25th annual Boston Music Awards. As usual, the list of nominees demonstrates that Boston is indeed an eclectic music town. Local acts (and national acts with strong local ties) will be lauded in 30 categories, spanning a wide array of genres from rock to rap, jazz to folk, electronica to Americana. We previewed the big night with a couple of guys who know from local music.
